Humira - has anyone had success with getting it at a lower cost?

I am going on Medicare this summer and am very concerned about the price I will have to pay for Humira. It is a drug that works well for my condition and I am worried it will be too expensive. Has any one else had success with getting a lower cost?

I am taking Humira and am on Medicare. I only have to pay $75.00 for my part of the total cost, but am not sure if my secondary insurance pays part or not. I was afraid that medicare would not pay for it, but so far it is working out. Humira has been so helpful for my problem and after 20 years I am able to have a much better life because of it. Hope you can stay on it.
